LOOSE-LEAF BINDER.

Application filed. August 31, 1927. Serial No. 216,707.

My invention relates to loose leaf? binders of the character embodied in my co-pending ap" lication, vSerial No. 186,723, filed April 26, i9 in this type of hinder a cover is provided composed. oi? sections which are exiicnsihly connected to a hack section for the purpose acconnnodating variable numbers of leaves or sheets and held inv binding relation to the latter by straps extended into and Secured in pockets piIlCliQfl in the back edges of the sheets. 'llhe straps which are usually formed of metal are associated with the cover to holdiihe sectiims in adjusted position, and

i'o effect a new ilCljllSidilQlli) oi. the cover sections a. reipiircd when the number of sheets is appreiiably increased it is necessary to detach the straps by removing a locking rod, shi'ir the straps to the position desired, and replace the locking rod in order to maintain the straps in the newly adjusted position. Also, tov secure the cover to the sheets, it is necessary to operate a locking .mcclmnism thusimpcding release of thecover when it is d wired to ire addii ional sheets or to remove any oi the present sheets. Each time a lock or release of the cover in respect to the sheets made, bending oi the strap is reipiircd and as hey are formed oi? metal, Iwpr-ttilfll bending and straightening soon causes i'l to split or break time necessitatsirops. purpose of my invention to provide a. slcaf hinder which overcomes the above rexii-ed disadvantar' by substituting rigid i mic or otherwise extcnsibiy con ected 'i.i.-.nii'iers for the straps, cmmccting the members directly to the top and bottom cover seciions. and connecting such sections to the hack remion by resilient elements which operte auiomatically to adjus'st the cover to accommodate variahie numbers of sheets in accordance witl'i an zu'ljusiznient oi the telcscopic nien'lbers.

i will describe only one form of loose leaf r embodying my invcn tion and will then out the novel features in claims.

Fig. .11 is a view showing in perspective the en' ire binder with the main parts thereof separated but in proper positions for association with a plurality of leaves.

Similar reference characters refer to simihnparts in'each of the several View.

Referring specifically to the drawings, my invention, in its present embodiment, comprises a cover including rigid top and bottom sections Ti and 13, respectively, and a. flexible back section F, which serves to connect the other two sections to form a cover for a plurality of sheets of paper S which is capable of being openedand closed in the manner of a book. The sections '1 and B are constructed to provide compartments and 16 therein opening into the inner ends of the sections and into which the ends of the back section F are extended and movable, all in a manner to ai ow a longitudinal adjustment of the top .1 bottom sections on the back section so as to vary the spacing of the confronting ends of the top and bottom sections and to thereby vary the capacity of the binder as a Whole to accommodate any number of sheets S, i. e. within certain limits.

As shown in Figs. 2 and S, relatively small plates 17 are riveted within the compartmeats 15 and 16, and similar plates 18 are riveied to the opposite ends ofthe back section F. These plates 17 and 18 areprovicled with hoolcshaped cars 19 by which coiled contractihle springs 20 are secured to the plates in the manner illustrated and for the purpose of yieldably urging the sections T and B inwardly upon the section F. The

portions thereof broken;

, The pin les' ot a button 30 which projer 36 end. 37 are recessed to pro to permit application or the to the plates and to insurethe resource 'reedom ot movement of the springs as stood.

Riveted to the inner sides of the top and hottomseetions T and B and at the confronting ends thereof are pair of plates and P, respectively, formed of metal or other suitable material and eonstitititing-stationery hing-cleaves with their edges const ucted to provide inane ides 22 arranged in 1 i having pintles extended t-luoug'h each p" urealso extended knuckles Qlnhd on the outer ends of memwill be underbottom cover ne'ctedto such other.

In the present instance such connectors, the memo gegen'ientwitl'i two sets rut t teeth 29 on 'theinner side of This pewlin engaging the i to secure the members t werdly "t ot-n o l other l moved to screens 31-in 'the inei'nbergd so as to be e" the finger and forced inwardly ur" is tree-ct the teeth, when the mom ugi eo lav t. e pawl s can he n'iioved laterally and longitudine ly to increaseor decrees their overull length and thereby vary the spacing of the top and hot llODICOVQT s ctions with respect to e, oth r.

These connectors are designed PL coafct with a locking; ineens tor segue securing the sheets within the cover and upon posts provided for the mrnose. lower pair of posts: hottoin l rise From is provided with ltnuckl-i geithrou 1 the pintle'torthe piste P exliends thereby hingedly connecting the her to the plate. An upperpeir of posts 35 depends from the stutionary s action 36 oi? a top her. T his top her is constructed intl'ie some manner the movable section having letchinglingers 40 adapted to engage and confine the connectors withln the pockets.

tion of the movable section the pockets 39 are open to permit the insertion or with drawn]. of the connectors, but in the o er cured stacked as the top vherdisclosed in my application liereinbetore ide pockets 30,

in one extreme posimioteo extreme position the pockets are closed by the finger l to confine the connectors there- The movable section can be actuated bythe provision 01"" a button 41 secured thereon. i I t The manner in which the bottom end top bars are adapted to be associated with the sheets S is clearlyillustrated in Figs. Sand 11, the sheets being-provided with openings to receive the'posts 32 and 35 and thus maintain them in stacked relation. 7

The connectors are adopted to he received within grooves or pockets 43 in the heck edges L the sition. within the cover. To secure thein therein the top cover sect-ion Tiselevated troin the position shown in Fig; 3 to that;

shown in 2 and 4 in which the connector ere swung to vertical position and within 'p-cclcetsZlQ. Bynow moving the 1 section 3? our theposition shown in Fig. 3 to that shomiyin l close the pockets and thus confine the contte 'ihusa, the sheets are se- While h e cover sections T and B through their hinged connections wlththe connectors are "free to he swung to open or closed position.

constructing; the connectors of extensible or telescopic members their overall len th can be varied as dcslred through 1 manipulation of the pewls 28 in the manner 33 and this bar, as shown; in detail-in Fl previously described, and to thereby very the spacing of the covers T and B to accomment or" the connectors in order to permit the required movement of the sections T and YB upon the section ll. in other words, as the top and bottom sections are moved outward lv, tor example, upon the heck section T, the springs will be extended to pennit such relative movement, and conversely as the sections and Bare moved inwardly upon the. heel; section the springs will contract thus at all tin-res preventing gathering or folding of the back section.

In ectuel practice, the buttons can be simultan ously pressed with the fingers to ot the sheets S, and when the pockets 39 Oil? the top bar are closed with the fingers it will be clear that the connectors are sheets with the pockets 39 of the section 36 in registration with the relation within the cover release the pawls 28 to permit the required adjustment 01" the cover sections to accommodate any particular number of sheets. Such adjustment is generally in excess of that actually required in order to permit the free insertion of the connectors within the poohets of the sheets and the top bar. After the connectors have been inserted into the pockets, the top section, which is now in substantially vertical position is pressed downwardly with su'llicient force to cause the members 26 and 27 to slide one upon the other until the inner edge oi the upper plate P comes into contact with the movable section 87 when the section 37 is moved to secure the connectors within the pockets. By operating the binder in this manner the cover is adjusted to snugly fit the sheets therein so as to cause all of the sections to lie contiguous to the sheets.

hen desiring to release the sheets, the

connectors can be readily removed from the pockets by sliding the section 2-37 to the position shown in Fig. 3, and by removing the top bar together with its posts 35, direct access can behad to the sheets to permit the addition of new sheets or removal of any oil the old sheets.
